The healthy condition of the hair depends, to a very large extent, on the intake of sufficient amounts of essential nutrients in the daily diet. Hair is made of keratin, a protein, which also makes up the nails and the outer layer of our skin. One of the primary cause of hair loss is a high amount of the male hormone, dihydrotestosterone (DHT) within the hair follicle. DHT is produced from testosterone in the prostate, various adrenal glands, and the scalp. After a period of time, an over abundance of DHT causes the hair follicle to degrade and shortens the active phase of the hair. General debility, caused by severe or long standing illnesses like typhoid, syphilis, chronic cold, influenza and anaemia, also gives rise to hair disorders. It makes the roots of the hair weak, resulting in falling of hair. An unclean condition of the scalp can also cause loss of hair. This weakens the hair roots by blocking the pores with the collected dirt. Heredity is another predisposing factor which may cause hair to fall. Silicon bags are inserted beneath an area of hairy scalp and gradually inflated with saline water over a six-week period. This causes the hair-bearing skin to stretch, thus increasing the amount of hair-bearing scalp. After removing the bags, expanded hair bearing skin is lifted and moved to an adjacent bald area where a similar sized patch of scalp has been excised. For men, hair loss is male pattern baldness. Yes, there are other types of hair loss, including rare conditions such as alopecia totalis and alopecia universalis, where the entire scalp and entire body, respectively, become completely bald due to a viral condition that is irreversible. There is also patch baldness, in which hair falls out in patches of the scalp. This is caused by stress or poor nutrition or adverse scalp conditions. But the hair will usually grow back once the cause has been rectified. The most familiar hair loss pattern is where the hair begins to recede in the hairline and the crown at roughly the same time. The hair in the mid-scalp or anterior scalp is often the last to go. But go it will, eventually leaving a man with the horseshoe of hair that is the telltale sign of typical male pattern baldness. The effectiveness of medications used to treat alopecia depends on the cause of hair loss, extent of the loss and individual response. Generally, treatment is less effective for more extensive cases of hair loss. Finasteride is not approved for use by women. In fact, it poses significant danger to women of childbearing age. If you're a pregnant woman, don't even handle crushed or broken finasteride tablets because absorption of the drug may cause serious birth defects in male fetuses.
Many people (wrongly) will drop a handful of shampoo on their head and then rinse it off. Shampoo must be worked through all of your hair, as well as the scalp and hairline. Blond hair may turn yellow, fade or become dull due to UV exposure. Even natural brunette hair tends to develop reddish hues from sun exposure due to oxidation of melanin pigments. Hair requires the same overall nutrition that the body does: plenty of fresh fruits and vegetables, grains and protein including lean meat and fish. Dietitians recommend foods high in biotin, including brown rice, bulgar, brewer's yeast, soybeans, green peas, lentils, oats, sunflower, seeds and nutritious nuts. Nutritionists advise healthy hair seekers to eat well-balanced diets that incorporate healthy proteins along with foods high in vitamins B, C, E, A and K. Hair instantly responds to the addition of protein-rich foods such as meats, eggs, cheese, seeds and nuts. Fish packs a double punch of protein combined with health building essential fatty acids and natural oils. We recommend you discuss your diet with a medical professional.
The innermost layer of hair is called the medulla and reflects light giving hair the various color tones it has. That's why hair color looks a lot different in sunlight than it does in the shade. The physical thickness and length of hair depends on what type of hair it is. Vellus hair is the fine fuzz type of hair that's often called peach fuzz. Its very fine and colorless and often almost invisible to the naked eye. Hair that is dark and very visible is known as Terminal hair. Terminal hair is the hair that we refer to when talk about hair. Whether a hair is a fine vellus hair or a thick dark hair depends entirely on the follicle that is producing the hair. In balding men thick terminal hair is often replaced by fine vellus hair. This is a result of the hair producing equipment, the follicle, suffering physical damage and being unable to produce terminal hair. About 90 percent of the hair on a person's scalp is growing at any one time. The growth phase lasts between two and six years. Ten percent of the hair is in a resting phase that lasts two to three months. At the end of its resting stage, the hair is shed. When a hair is shed, a new hair from the same follicle replaces it and the grow-ing cycle starts again.
DefinitionsAlopecia Areata
- Alopecia areata is a hair loss condition which usually affects the scalp. It can, however, sometimes affect other areas of the body.
Hair loss
- A progressive, diffuse loss of scalp hair in men that begins in the twenties or early thirties, depends on the presence of the androgenic hormone testosterone, and is caused by a combination of genetic and hormonal factors. Also called androgenetic alopecia.
Hair transplantation
- Hair transplantation is a surgical procedure used to treat baldness or hair loss (alopecia). Typically, tiny patches of scalp are removed from the back and sides of the head and implanted in the bald spots in the front and top of the head.
Protein
- Important building blocks of the body, composed of amino acids, involved in the formation of body structures and controlling the basic functions of the human body.
- Complex organic molecules made up of amino acids. Proteins are basic components of all living cells and are therefore among the principal substances that make up the body.
Ringworm
- The term "ringworm" refers to fungal infections that are on the surface of the skin. The early belief was that the infection was due to a worm, which it is not, although the name has stuck. Some of these fungi produce round spots, but many do not.
Thyroid
- A gland in the throat that produces hormones that regulate growth and metabolism.
- A large gland in the neck that functions in the endocrine system. The thyroid secretes hormones that regulate growth and metabolism.
Alopecia
- A hair loss, baldness, and epilation.
- Alopecia, also called hair loss, baldness, and epilation, is a common side effect of chemotherapy and radiation therapy.
Baldness
- A progressive, diffuse loss of scalp hair in men that begins in the twenties or early thirties, depends on the presence of the androgenic hormone testosterone, and is caused by a combination of genetic and hormonal factors. Also called androgenetic alopecia.
Biotin
Follicles
- A follicle (from the Latin folliculus) is a term to describe a small spherical group of cells containing a cavity.
Grafts
- To transplant or implant surgically into a bodily part to replace a damaged part or compensate for a defect.
Hormone
- A substance, usually a peptide or steroid, produced by one tissue and conveyed by the bloodstream to another to effect physiological activity, such as growth or metabolism.
Scalp
- The skin covering the top of the human head with its attached hair.
Stress
- Importance, significance, or emphasis placed on something.
- The relative force with which a sound or syllable is spoken.
- Accent or a mark representing such emphasis or force.
- An applied force or system of forces that tends to strain or deform a body.
- A mentally or emotionally disruptive or upsetting condition occurring in response to adverse external influences and capable of affecting physical health, usually characterized by increased heart rate, a rise in blood pressure, muscular tension, irritability, and depression.
- A state of extreme difficulty, pressure, or strain.
- A physical and psychological response that results from being exposed to a demand or pressure.
